Originally, "Bad Boy" includes a choreography where Seulgi pretends to shoot with a gun.

As you can see, there is no resemblance to a gun here and the part was slightly tweaked at the North Korea concert. 

Reports stated that all the performances were checked ahead of time and the North did not find issue with Red Velvet's songs or dances. As a result, fans believe Seulgi made the change herself in consideration of the North Korean audience who might be sensitive to such a dance move. 

Comments praising Seulgi stated, "I love that part but I think she made a clever change. Nice!", "It's cute how she changed that herself", "Hahaha what a professional", "I was worried about that part. She made a good change."
